Houston ? Astronauts aboard the shuttle Discovery and the international space station reveled Sunday in their successful solar wing repair before closing the hatches between their linked spacecraft and preparing to part ways.

Crew members were transferring supplies and equipment between Discovery and the station Sunday morning. The hatches were closed Sunday afternoon, giving the shuttle crew an afternoon to relax.

The shuttle is set to pull away today. Discovery is scheduled to land on Wednesday.

The space station’s three occupants have a lot of work to do after Discovery leaves.

They need to move the pressurized compartment that was delivered and installed by the Discovery crew – and conduct three spacewalks – before the planned December launch of shuttle Atlantis carrying the first of two new laboratories.

NASA still has to figure out what to do about a malfunctioning rotary joint that turns another set of the station’s solar power wings toward the sun. Last weekend, a spacewalker found steel shavings inside the joint, apparently the result of grinding parts.

Discovery’s crew will bring samples of those shavings back to Earth to help pinpoint the source of the trouble.
